Electronics are, together with programming my biggest hobbys and i got early into it because my dad is an electrician. He showed my the basics of Electronics by connecting components together with aligator clips to create basic circuits like a simple blinking circuit or he showed me how a SCR works. I was still in kindergarden when i received my first electronics kit, a basic construction kit with resistors, caps, switches... which are mounted on plastic strips that can be connected together using press-studs.In primary school, as a easter gift i received my first real, so called "Franzis" electronicy kit, a kit about experiments with low-power lasers. Those kits basically contain a breadboard, components and a book about the basics of electronics and the topic. I got "a few" more of those kits over the years, and this is how i basically learnt a lot of things about electronics. In 3rd grade for example, i built an 2-Digit 7-Segment counter with blinking overflow detection from jellybean logic on a breadboard. In the Age of ten i got another Franzis kit, but this time with an Arduino in it, so you can say i can program arduinos for 5 years.

My entry:

PS: I had a lot of more footage to show, was quite difficult to get it all in a 2-Minute Video. I completely left out any old projects of mine and only showed one recent project, an other one is an high-speed photography flash, but i didn't put any footage about it in the video. This was another project i wanted to show where a better scope would help, but there was no time left in the vid. Also i commented the scenes where i used my scope but again, there was no time left.

You are allowed to win things in germany if you are are 14 or older, and i am 15, so: no problem. I would also pay the taxes for sending it to germany.

Hi Dave, we are a Robotics club from Technical University of Sofia, Bulgaria. Right now we are having more that thirty members for 2017, so the scope will not only be in good use but it will be in good use for many students. You can see a lot of pictures of our projects in our gallery.

We are starving for a nice DSO like this;for something that happens very fast and violently (hey! we are talking about the coil gun here!), all the parasitic starts to matter, a DSO seems like the only way out.

we actually spent 20hrs+ on a way better video, but unfortunately, well, things went wrong.. (hard drive stopped chuuching)Good on ya, mate.

My aim is to build low cost instruments and enable as many people all over the world, to access a scope and invent(be it in Africa, China, India etc), utilising all sorts of interfaces that might be readily available in desktop PCs, I hope it is doable, like ATAPI, hacking in flash/sar ADCs 2x8bit or 1x16 into parallel ata, pretending to be a cd-rom or hdd, maybe even packing data into SATA LVDS and ingesting data at up to 6gbps etc more info and ideas: GinScope project page: https://hackaday.io/project/19374-ginscope-science-toolbox-oscilloscopeWhich should evolve into GinLab - Science ToolBox, all accessible, programmable & controllable over the network (if UK does not kill me first , but that is another story)Working mvp/first prototypehttps://github.com/soholt/GinScope (and some extra thoughts/philosophy)

Currently my only instrument is VICY VC99 multimeter Proper scope & logic analyser would provide me with a solid reference and debugging abilities

Hi man! It's Leandro, from Argentina. I am writing to send you my video. I put a lot of effort into it and I am sure you will like it and have fun watching. I would like you to remember that I am only seventeen years old and I don't have any kind of financial support. I have managed to do almost every project I want (specially by recycling almost all components!) but making a scope is way to hard. i hope it is not too late, in arg is not midnight yet.Have a great day!

we are a group of electronics and making enthusiasts of L'Aquila - Italy. In 2015 we reused a dismissed laboratory of an high school in our town to settle a Fablab.This video was shot one evening while we were organizing a fair.Thanks for the opportunity!

Hi Dave and David,I'm a yungster from Hamburg in Germany, 14 years old. I begun with robotics(NXT 2.0) when I was 9, now I am more into digital electronics, because it just fascinates me that i can run a complex simulation of something on computer whitch consists of different charges and voltagelevels. Now threre is this plan in my head to build a chronograph. Thats the first thing for witch I need this scope because I need to measure an accurate clock frequency otherwise I would get inaccurate results. Also alot later in maybe 3 to 6 months I want to try to connect my planned 8bit Computer with the chronograph to not show the counted steps but an allready calculated velocity.

I would of couse like to get the scope but chosse the one how you think is the best.Have a good Day

Hello, My name is John. I have 13 years old and I am from Poland so sorry for my English and accent

I started with electronics when i was eleven. I get and Arduino for Christmas. I was also interested in programming. I started watching EEVblog and I so much like your mailbag videos.I have built robots, games on 2x16 screen and things like that. Then i get wifi-module and made something like smart home with turning leds on, temperature, clock, timer etc. Then I have started to learn clean C for microcontrollers. I wanted to have an oscilloscope to better understand what is happening in my circuts, but I did not have money. So I made my oscilloscope from Arduino and Processing. It was not precise, slow and had range up to 5 volts Without oscilloscope it's hard to me to understand how FM, AM, coils, AC and curcuits work. I would be very happy if I had won that device

First i recorded video of 10 minutes length because i have so many things to show You.Here is link:

In summary: -open source sampling oscilloscope usable with a sound card: 100Ms/s and 100MHz bandwidth. -can open source and maintain a netlist converter from LTSpice to Kicad which I used to design the PCB for the above project The sampling oscilloscope can be easily modified to reach 1Gs/s and 1GHz bandwidth using better components (and better tools for testing). The same architecture (fast comparators driving diode bridges) can be used for a bandwidth of several GHz and 10Gs/s or more.

Here is my entry for the Scope giveaway. The time on the video thumbnail says 2:01 but when you play it, it is 2:00 flat and should live by the rules of the contest. I hope you enjoy. The remaining text below is not intended to be part of the judging info but to clear up some choices for those that are curious.

Some may be confused as to why I’m using ethernet in my designs due to higher latencies and non-deterministic behavior. I went with this technology because knowledge on the internet seemed to be more approachable than a fabric like Infiniband and learning how to use sockets in C was surprisingly straight forward. As far as addressing other latency and non-deterministic performance issues I will quickly mention that I am using only point to point systems for the actual link controllers as well as UDP in the hopes of alleviating just such fears. Finally, this is all just for fun so if I don’t get ideal performance with ethernet I can try something new next go around! I will have learned a lot from this experience by then too.

Hi Dave I'am Don from Florida , USA USA , I got a reminder to watch your newest video today and its a winner CHICKEN DINNER ! Unfortunately this year when Keysight was doing their "Scope month" I was not able to win I did however enter everyday not knowing that because I live in Florida I could not win a FREE SCOPE , so maybe thing's will turn around for me . I do however have a scope if you want to call it that , I made it from a cheap Chinese kit and you think your scope is crusty I have the flagship of CRUSTY SCOPES a genuine DSO138 2.4 TFT Digital Oscilloscope Kit DIY . After buying one kit and it did not work I bought a assembled kit that did not work so I returned it and ordered a third one ( I still had the first kit ) the third one was a fail so with 2 kits I made one that worked , it was the switch's I think that they are the finest switches on the planet HA HA ! ( same with my scope ) Lately I have stopped building " Joule thief's " and have been working on a CFL light that will run under 1 volt , I have got one to run off of 1.2 volts and have not given up after 4 months using scrap parts out main distributor ( Radio Shack ) has gone out of business so I have turned into a cannibal 24 / 7 running adds for broken electronics to the point "The Men In Black " showed up at my door on 9 / 9 / 2016 wanting to know what I was building , no joke , I was pulled over the next day by most of our local police for the same reason . A real scope will change my life and I can use it to trouble shoot the junk kit's I keep buying from China and start really inventing some cool stuff I have a lot of ideas , but one major thing is holding me back can you guess what that is ? I 'am disabled but not looking for a pity party just a working scope . If I get one I will cherish it and as my first born I will name it Dave the master of electrons , I will have that professionally engraved on its face plate . Well I'am done ranting but keep me in mind , I will use this scope everyday even if my wife gets a little mad for me zoning out on her watching waveform's . Now I will try and post part of the video I made , my camera was not running when I started showing off my toys I made but caught this around half way through . Thanks for the great videos I enjoy them so much especially mail bag when you do the tear downs , my favorite video to this day was when you took the Keysight multi meter and gave it a stress test taking it on a real "Road trip" 88 KMH and then at the end tossing it off the dam , I don't know why I loved that video so much maybe it is some deep seated resentment towards Keysight for excluding Florida from their contest , HE HE HE ! I have that bookmarked for when I'am feeling a little down . Looking forward to more videos I really do enjoy them , Oh I was the person that called out Keysight for the probe artifact tapping the BNC connector after watching your post EEVblog #14 - An unusual oscilloscope phenomenon! then EEVblog #20 going on to EEVblog #21I brought this up live while Daniel was praising their new scopes and had him do the BNC tap test he was flustered and because I could not win after entering for a month straight everyday I was falling off my chair , thanks for making my day , they did say that they would get back with me but the never did . I wonder why ? Thanks for all that I have learned from your videos and I hope I have a chance of going from REAL CRUSTY TO A FERRARI . You have a great day in upside down land Australia not Austria ! ! !

I could not load my video or edit it but it is under 2 minutes and is on youtube at this site & and would make a great birthday present it is not today but yesterday , sorry about not being able to do this youtube stuff like a pro

My name is Bart, I am a hamradio from the netherlands for over 35 years.my video :

I create a lot of things over the years and started using microcontrollers and designing things around it about 5-6 years ago.Eevblog and a lot of other stuff on the internet gives me a lot of nice ideas to work on.

The radio is special to me, as it was a build for my late mother, she didn't understand modern radios any more, as the only knob on them nowadays is 'volume', the rest s via pushbuttons and menu's. So i created a radio with just a volume and a station knob. All the local cableradio stations are preprogrammed. Pushing the knobs (encoders) you still can set audio, time, display etc.It's actually using 2 Atmega328p's, one for the display, receiving commands via i2c and using 'stylesheets' to display data send by the other one controlling the tuner and audio components.She sadly died a while ago, and i'm working on converting it to a DAB radio.

The GPSDO's are two different approaches, one with a PLL chip, which is build by several HAM's already, the other one is an approach to create more long term stability. I started it using standard ttl logic, but the goal is to redesing it using a small fpga or cpld.

New projects in a design and prebuild-fase (i search on hamfests etc for components) are a Universal Multi-input DC to 3GHz power meter to display output power and SWR. It will accept all kinds of powercouplers and heads, and can be calibrated over a large range of frequencies and power ranging from microwatts to kilowats.There is also a dual (or tri-) band (2m/70cm/23cm) transceiver in the making, but the difference with available quipment i that the transceiver has no knobs/dials/display. Everything will be done via a small battery operated remote control box via bleutooth, and audio is also going over bleutooth using regular mobile devices.Also a 1.3GHz and 2.3GHz preamplifier are in the collecting parts fase, as a 13cm power amp, and an ATV transmitter.

So you see, ideas and projects enough, and the reason of entering the contest is that my 2-channel rigol is too small for the job. I tried to get my hands on one of the special offer RTB's, but in europe it was not a public offering. Buying one is not an option, it is just too expensive.

Thanks for your time, and i will follow your blog for as long as i can.

I know I'm posting after the last date for submission. I completed the video yesterday but couldn't upload to YouTube But I'm posting it anyway. It's okay if you don't consider this video for the contest (at least you'll see it I hope )
